    Today in class, we used the entire class to work on Page 212-214.  The solutions are attached here.  

    For homework, review for the assessment.

  • Absolutely Finished (maybe not...)

    Posted by Kurt Waldner on 1/22/2020

    Today in class, we checked Page 207-209.  We looked at the transformations of the absolute value equations, discussed a way to compare the graphs with slopes and symmetry.  We also looked at vertical and horizontal movement.  Once we finished, we started working on the review for the upcoming assessment.  This is not homework.  The remainder of class today and all the class tomorrow will be devoted to students being able to work on any of the review problems and ask any questions on the review problems.  We will be focusing on Page 212-214 #5-34.

    For homework, review for the upcoming assessment.

  • Absolute Value Graphs

    Posted by Kurt Waldner on 1/21/2020

    Today in class, we quickly reviewed the transformations that happen to an absolute value equation (see previous post).  We then used the majority of class to work on the assignment.

    For homework, complete Page 207-208 #10-18 (evens), 21-29, 36-44 (evens), and 56-59.

  • Multivariable Absoute Value Equations

    Posted by Kurt Waldner on 1/17/2020

    Today in class, we used the entire period to investigate the transformations of the absolute value equation.  We looked at adding and subtracting outside and inside the absolute value.  Here are our discoveries:

    |x+#| - The parent graph will move # units to the left.
    |x-#| - The parent graph will move # units to the right.
    |x|+# - The parent graph will move # units up (y-intercept).
    |x|-# - The parent graph will move # units down (y-intercept).

    When we multiplied a number, we also noticed some interesting trends based on the location of the number.

    #|x| - If positive, the graph will open up.  If negative, the graph will open down.  If |#|>1, the graph will close together (the larger the number, the closer together).  The graph will move toward the y-axis.  If 0<|#|<1, the graph will open up more (the smaller the number, the flatter the graph.  The graph will move toward the x-axis.  

    We will look into these graphs more on Tuesday.

    There is no homework.  Have a wonderful long weekend.  GO LIONS!!

  • NO CLASS (Field Trip/Sickness)

    Posted by Kurt Waldner on 1/16/2020

    Due to half the class being out, we had a review session for any student that wanted extra practice.

    There is no homework.

  • Returned Quiz and Multivariable Absolute Value Equations

    Posted by Kurt Waldner on 1/15/2020

    Today in class, we returned and checked the 27 point quiz on solving and graphing absolute value inequalities.  After going over the results, we started to work on multivariable absolute value equations.  We will look at these equations more closely tomorrow.

    There is no homework.

  • Review Absolute Value Inequalities

    Posted by Kurt Waldner on 1/13/2020

    Today in class, we reviewed the six absolute value inequalities from the review worksheet.  We discussed the various twists that can happen with these problems (and or or, switching the sign, no solution).  This was a good review for the quiz tomorrow.

    For homework, review for the quiz on graphing and solving absolute value inequalities.

  • Absolute Value Inequalities

    Posted by Kurt Waldner on 1/10/2020

    Today in class, we finished our initial discussion on absolute value inequalities.  We worked through a few special cases and then worked on a review worksheet.  The examples are attached here.

    For homework, complete the review worksheet.  We will have a quiz on Tuesday.  Have a warm weekend.  GO LIONS!
